text: The best aquaculture model of grass carp was studied in two ponds by different stocking species and ratio. The two ponds with the same management and the same formulated feed, the result showed that productions of grass carp in 1# pond 9754kg, common carp 1500 kg,silver crucian carp 492.5 kg,silver carp and big head carp 1383 kg. the production 1312.95kg,the profit 4786. 40 yuan in 666.7m~2, The ratio of profit 1: 1.70, The feed coefficient 1.70, respectively. Yields of 2# pond was grass carp 4482.2 kg, big head carp 1760.0 kg, the average production 624.22 kg. the average profit—55.0 yuan in 666.7 m~2, the ratio of profit 1 :0.98,the feed ccefficient 1.24, respectively. The result indicated that suitable breeding pattern was the key of success and high profit on major farming of grass carp in pond.
